 Please build the "AudioValidationLib" target in CMake.
 It would generate a dynamic library for CFFI to use.

 The test case should be a python file with a class inherited from AudioTest.
 You would need to modify CWrapper.cpp to add new function wrappers for the new test case.
 The class should have a method named "run" which will be invoked by the main.py.

+### Environment Setup
+```
+$ cd ImageProcessing
+$ python -m venv Img.venv
+$ source Img.venv/bin/activate
+$ pip install -r requirements.txt
+$ deactivate
+```

+### Execution
+```
+$ source Img.venv/bin/activate
+$ python compareImg.py <PATH/TO/Image1> <PATH/TO/Image2>
+$ deactivate
